Marginal note:Repetition

(3) If the sum of the values for S3 and S4 that are determined, respectively, under subsections (1) and (2) is less than -1, the application of those subsections is to be repeated, with the shortest period referred to in paragraph (1)(b) being lengthened by three years for each repetition, until the sum of those values is greater than or equal to -1. All references in these Regulations to the value for S3 determined under subsection (1), the value for S4 determined under subsection (2), the period determined under subsection (1) or the rate calculated under subsection (1) or (2) are to be read as that value, period or rate following the final application of those subsections.

Marginal note:Deemed change to contribution rates

(4) If the rates calculated under subsection (2) exceed the corresponding first additional contribution rates for self-employed persons, excluding any past temporary increases in those rates resulting from the operation of these Regulations, by more than 0.0001,

(a) the first additional contribution rates for self-employed persons are deemed to equal the corresponding rates calculated under subsection (2);

(b) the first additional contribution rates for employees and employers are deemed to equal the corresponding rates referred to in paragraph (a), divided by two; and

Marginal note:Deemed temporary change to contribution rates

(5) For each year for which the first additional contribution rate calculated under subparagraph 115(1.1)(d)(ii) of the Act would include a temporary increase if benefits were determined in accordance with sections 14 and 15 and subsection 5(4) of the Calculation of Contribution Rates Regulations, 2021 did not apply,

(a) the first additional contribution rate for self-employed persons is deemed to equal the sum of the first additional contribution rate for self-employed persons for that year, as adjusted in accordance with subsection (4), if applicable, and the amount of any temporary increase, rounded to the nearest multiple of 0.01, that is applicable to that year;

(b) the first additional contribution rate for employees and employers is deemed to equal the rate calculated under paragraph (a), divided by two; and

Marginal note:Target benefit multipliers

**13** For the purposes of sections 14 and 15, the interim target benefit multiplier is the value determined by the following formula for the last year of whichever of the applicable periods referred to in paragraph 11(1)(a) or 12(2)(a) or determined under subsection 12(1) is the shortest and the final target benefit multiplier is the value determined by that formula for the last year of the applicable period referred to in paragraph 11(1)(a) or determined under subsection 12(1):

BM_{t–1} × [(1 + S3 + S4) – (S3 + S4) × (PI_{t–1} / PI_{t})]

where

- BM
_{t–1} - is the value of the benefit multiplier for the year before that year;
- S3
- is the value for S3 determined under subsection 12(1), if applicable to that year;
- S4
- is the value for S4 determined under subsection 11(1) or 12(2), if applicable to that year;
- PI
_{t–1} - is the Pension Index for the year before that year, based on the assumption of future inflation set out in the most recent report prepared for the purpose of section 115 of the Act; and
- PI
_{t} - is the Pension Index for that year, based on the assumption of future inflation set out in the most recent report prepared for the purpose of section 115 of the Act.

Marginal note:Determination of new benefits

**14**(1) Benefits that become payable in a year are to be determined by multiplying the corresponding legislated benefits by the benefit multiplier for that year.Marginal note:Benefit multiplier — no interim adjustment

(2) If the interim and final target benefit multipliers are equal, the benefit multiplier is equal to

(a) the value determined by the following formula, for each year for which that value is greater than the interim and final target benefit multipliers:

BM

_{t–1}× [(1 + S3 + S4) – (S3 + S4) × (PI_{t–1}/ PI_{t})]where

- BM
_{t–1} - is the value of the benefit multiplier for the year before that year,
- S3
- is the value for S3, if any, determined under subsection 12(1),
- S4
- is the value for S4, if any, determined under subsection 11(1) or 12(2),
- PI
_{t–1} - is the Pension Index for the year before that year, and
- PI
_{t} - is the Pension Index for that year; or

- BM
(b) for each subsequent year, the interim and final target benefit multipliers.

Marginal note:Benefit multiplier — interim adjustment

(3) If the interim target benefit multiplier is greater than the final target benefit multiplier, the benefit multiplier is equal to

(a) the value determined by the following formula, for each year for which that value is greater than or equal to the interim target benefit multiplier:

BM

_{t–1}× [(1 + S3 + S4) – (S3 + S4) × (PI_{t–1}/ PI_{t})]where

- BM
_{t–1} - is the value of the benefit multiplier for the year before that year,
- S3
- is the value for S3 determined under subsection 12(1),
- S4
- is the value for S4 determined under subsection 12(2),
- PI
_{t–1} - is the Pension Index for the year before that year, and
- PI
_{t} - is the Pension Index for that year;

- BM
(b) the value determined by the following formula, for each year to which paragraph (a) does not apply and for which that value is greater than the final target benefit multiplier:

BM

_{t–1}× [(1 + S3) – S3 × (PI_{t–1}/ PI_{t})]where

- BM
_{t–1} - is the value of the benefit multiplier for the year before that year,
- S3
- is the value for S3 determined under subsection 12(1),
- PI
_{t–1} - is the Pension Index for the year before that year, and
- PI
_{t} - is the Pension Index for that year; or

- BM
(c) for each subsequent year, the final target benefit multiplier.

Marginal note:Determination of other benefits

**15** Benefits, other than those that become payable in a year, are to be determined, for each year to which paragraph 14(2)(a) or (3)(a) or (b) applies and for the first year to which paragraph 14(2)(b) or (3)(c) applies, by multiplying the previous year’s benefits not by the ratio referred to in paragraph 45(2)(b) and subparagraphs 56(2)(c)(ii), 58(1.1)(b)(ii) and 59(c)(ii) of the Act, but by the value determined by the following formula, as the case may be:

(a) for each year to which paragraph 14(2)(a) or (3)(a) applies,

(1 + S3 + S4) × (PI

_{t}/ PI_{t–1}) – (S3+ S4)where

- S3, S4, PI
_{t}and PI_{t–1} - have the same values as in the applicable paragraph;

- S3, S4, PI
(b) for each year to which paragraph 14(3)(b) applies,

(1 + S3) × (PI

_{t}/ PI_{t–1}) – S3where

- S3, PI
_{t}and PI_{t–1} - have the same values as in that paragraph; or

- S3, PI
(c) for the first year to which paragraph 14(2)(b) or (3)(c) applies,

(FTBM / BM

_{t–1}) × (PI_{t}/ PI_{t–1})where

- FTBM
- is the final target benefit multiplier,
- BM

- PI
_{t} - is the Pension Index for that year, and
